Dear Inge Anundskås :
We plan to release a DAMBRK Module this summer. Pricing has not been established at this time. However, I will get Bob Klemp in touch with you concerning upgrading to RiverCAD 4.0.
The DEM Module can import ESRI ARC/INFO and ArcVIEW gridded data. When you import a file, you need ot specify which format you are importing.
If you have any additional questions or need any further information, please contact me again.
Sincerely,
Chris E. Maeder, M.S.
